Drug & supplement interaction

Wild Carrot + Atezolizumab

Atezolizumab brand name: Tecentriq.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Wild Carrot and Atezolizumab in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Wild Carrot and Atezolizumab

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Atezolizumab and Wild Carrot in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Wild Carrot safety at a glance

Wild Carrot overall Use caution Generally used in folk medicine, but human safety data are limited and the seeds may carry more risk.
Pregnancy Likely Unsafe When used orally. The seeds, oil, and above ground parts can cause uterine stimulant, abortifacient, and menstrual stimulant effects. BREAST-FEEDING: Read the full pregnancy detail
Breastfeeding Avoid Not enough safety information is available, so it is best avoided while breastfeeding.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Atezolizumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Atezolizumab is filed under 2 classifications — antineoplastics, immunosuppressants. Wild Carrot has documented interactions with 4 drug classes — the most serious being antihypertensive drugs (moderate), estrogens (moderate) and lithium (moderate) — and none of Atezolizumab’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Wild Carrot and Atezolizumab May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

From our pharmacist’s overview on the Atezolizumab page

“Atezolizumab (Tecentriq) is cancer immunotherapy, a drug designed to release the brakes on your own immune system so it can attack tumors.

About Wild Carrot

What is Wild Carrot?

Wild Carrot
  • Urinary and bladder complaints
  • Digestive upset and gas
  • Menstrual support
  • Supporting milk production
  • Mild diuretic (water pill) effect

Wild carrot is a traditional herb (the wild ancestor of the garden carrot) used mostly for urinary, digestive, and menstrual complaints. High-quality human studies are lacking, so its benefits are unproven, and it should be avoided in pregnancy because of traditional use to affect the uterus. Talk with your pharmacist or doctor before using it.

Daucus carota · Apiaceae · Seeds, root, leaves, and flowers; sometimes the essential oil · Tea, dried herb, tincture, capsules, seed extract, essential oil

An interaction check asks whether these two react with each other — it does not ask whether Wild Carrot is a good idea for someone in your situation. Here is what our Wild Carrot record says about it on its own.

Wild Carrot: dosing

There is no well-established, standardized dose for wild carrot. Traditional preparations vary widely, and the strength of teas, tinctures, capsules, and seed extracts is not consistent between products.If you choose to use a wild carrot product, follow the directions on the label and do not exceed the recommended amount. Because quality and potency can differ, choose products from reputable brands.

About Atezolizumab Injection

What Is Atezolizumab Injection Used For?

Brand name: Tecentriq

Tecentriq (atezolizumab) is used to treat a range of cancers in adults. It can be used alone or combined with other cancer medicines depending on the cancer type and stage. Approved uses include non-small cell lung cancer (NSCLC) — both after surgery and in metastatic (spread) disease — extensive-stage small cell lung cancer (ES-SCLC), unresectable or metastatic hepatocellular carcinoma (liver cancer), BRAF V600 mutation-positive melanoma, and muscle invasive bladder cancer after surgery.

Tecentriq is also approved — as a single agent — for adult and pediatric patients aged 2 and older with unresectable or metastatic alveolar soft part sarcoma (ASPS), a rare soft tissue cancer. Several of these uses require tumor testing (such as PD-L1 expression or specific gene mutations) before Tecentriq is selected as treatment.

Taking Wild Carrot and Atezolizumab Together: Common Questions

Is it safe to take Wild Carrot with Atezolizumab?

Do Wild Carrot and Atezolizumab have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other.

How was the Wild Carrot and Atezolizumab combination checked?
Interactions in our licensed database are recorded against drug classes. Atezolizumab is filed under 2 classifications, and Wild Carrot has documented interactions with 4 drug classes — none of Atezolizumab's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Wild Carrot interact with any other medications?
Yes. Wild Carrot has 475 documented drug interactions in our database — Atezolizumab is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
